Bruce from Fort Myers, Fl writes,

Can Gordons Ornamec Over-the-Top Grass Herbicide be used to kill bermuda grass in an established St. Augustine lawn?


No, Gordons Ornamec Over-The-Top Grass Herbicide is not safe to use in St. Augustine grass. Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the St Augustine as well.  In your situation it is recommended to spot treat the Bermuda with a non-selective glyphosate product and kill it directly, and then replant St. Augustine in those areas.
